Dennis Gove commented on SOLR-6465:
-----------------------------------
I was able to get this to apply to 5.5 by first applying
https://issues.apache.org/jira/secure/attachment/12775961/SOLR-6273-plus-8263-5x.patch
which is attached to SOLR-6273. I did need to make some minor tweaks to that
patch as it didn't apply perfectly cleanly and left a couple of minor
compilation errors (visibility of certain variables to extension classes).
This patch also required a few tweaks as it didn't apply cleanly but more-so it
appears the patch contains Java lambdas which do not work in Java 7 or below.
